Rooftop Screening Services — NYC
Custom Mechanical Equipment fabricates RTU screening, HVAC screens, and mechanical equipment enclosures for commercial rooftops across New York City — office towers in the Financial District, hotels along Broadway, mixed-use in Long Island City, and institutional buildings throughout the Bronx and Queens.
RTU screening NYC by equipment type
Every system below is drawn to your roof plan and NYC zoning context — visibility corridors, LPC review where landmarked, and DOB submittal requirements. Panels ship cut to approved drawings. No field-cut kits.
Solid Panel Screening
When zoning or design guidelines require the RTU to disappear from street view, solid 26-gauge steel panels are the standard path. We fabricate screen walls that conceal packaged units, exhaust fans, and cooling towers from pedestrian corridors like 5th Avenue, Broadway, and the High Line sightlines — without leaving raw, unfinished metal on the roof.
Every solid panel run is drawn to your equipment map and roof edges. Heights are set relative to your parapet line, not a catalog dimension. Finish schedules include gauge, coating, and color for DOB submittal.
Perforated Panel Screening
Mechanical engineers specify a free-area number; you need a perforated pattern that hits it without choking the coil. Perforated faces soften the visual impact while maintaining airflow. NYC allows perforated panels when the open portion of the face is 50% or less.
We define open area in the shop drawing, not with a field drill. Your mechanical engineer reviews the pattern against manufacturer clearances before fabrication starts.
Louvered Screening
Louvered layouts give you defined open area with a more architectural profile than raw perforated sheet. We coordinate louver spacing and orientation with your mechanical schedule so service access and airflow both survive plan review.
Common on Midtown office towers along Sixth Avenue, Williamsburg mixed-use along the waterfront, and Long Island City conversions where screening is visible from street level, the East River ferry, and adjacent rooftops.
Non-Penetrating Systems
Membrane warranties, existing insulation, and landmark restrictions often prohibit new roof penetrations. Ballasted and post-mount base systems meet your engineer of record's requirements — not a kit that usually works.
Non-penetrating systems are especially relevant in LPC landmark districts — Greenwich Village, SoHo, Upper West Side, and Brooklyn Heights — where new roof penetrations require a separate approval layer before DOB. We coordinate ballast or post-mount details with your structural engineer and include them in the shop drawing package.
Snow & Cold-Climate Systems
NYC winters add drift and point load to every roof screen calculation. A wall that passes permit issuance but fails under snow load is not a wall we ship. We coordinate with your structural engineer so the screen survives winter, not just the DOB stamp.
Snow load coordination is built into our shop drawings from the start — attachment method, base design, and panel gauge are all sized for the load case your engineer specifies.
Schools & Hospitals
Montefiore campuses in the Bronx, DOE school renovations in Brooklyn and Queens, and hospital expansions in Manhattan have their own access, noise, and scheduling constraints. We fabricate screening for occupied buildings where freight windows and install sequencing matter as much as the drawing set.
RTU screening NYC requirements apply to institutional projects the same as commercial towers — all-sides screening, parapet-relative heights, and stamped shop drawings.
